Here are some lovely ladies for you folks! The first person to post a comment with the correct identity of all four fabulous females gets the original art. Don't say I never did anything for you!
Here's a color version I whipped up in Photoshop! I knew some of these likenesses weren't the best, but I thought they were fun drawings. Hopefully the color will aid in revealing their identities.
The contest is closed to my family and 'non-internet' friends.
